    Abstract

    Traditional economic interpretations have not been successful in explaining differences in

    saving rates across countries. One hypothesis is that savings respond to cultural specific

    social norms. The accepted view in economics so far is that culture does not have any effect

    on savings. We revisit this evidence using a novel dataset, which allows us to study the sav-

    ing behavior of up to three generations of immigrants in the United Kingdom. Against the

    backdrop of existing evidence, we find that cultural preferences are an important explana-

    tion for cross-country differences in saving behavior, and their relevance persists up to three

    generations.

    Introduction

    Savings are important drivers of economic growth and are pre-requisite to the sustainability of

    pension systems and the international balance of trade. The correlates of differences in saving

    rates have been well-studied in the literature and include the effect of demographics, differ-

    ences in income and growth rates, social security systems, tax systems and housing price differ-

    entials, and financial markets and liberalization [1, 2, 3, 4, 5, 6, 7]. However, even after

    controlling for differences in these covariates, a large part of the differences in saving rates

    across societies remain unexplained [8].

    One hypothesis is that savings respond to cultural specific norms. Previous evidence on the

    relevance of culture for saving behavior comes from [9]. The authors used data from the Cana-dian Surveys of Family Expenditures. They studied the saving behavior of first-generationimmigrants in Canada and test whether saving rates varied systematically by place of origin.

    All immigrants face the same institutional and economic environment, the one of Canada,

    therefore any systematic difference across places of origin, if any, could be attributed to cul-

    ture. The authors found that saving patterns did not vary systematically by place of origin.

    These findings formed the basis of the commonly accepted view that culture does not influence

    saving behavior.

    The original study [9] had various limitations: first, the sample of immigrants was small,

    second the classification of the place of origin was too broad (the authors did not have any

    information about the country of origin but only about broad geographical regions), and third

    wealth was not measured properly.

  • In this paper, we re-examine the hypothesis that culture matters for saving behavior, by

    looking at the saving behavior of three generations of immigrants in the United Kingdom and

    using data from the Understanding Society Survey, the largest UK household longitudinal

    survey.

    Like in the original paper [9], the identification strategy relies on the possibility to observe

    immigrants from different countries of origin in the same environment (in this case, the

    United Kingdom). This allows distinguishing cultural determinants of savings from factors

    like tax code, social security system and any other institutional and economic factor more

    generally.

    The Understanding Society Survey presents numerous advantages. First, it allows us to

    identify first, second (also defined children of immigrants: individuals born in the UK with

    parents born abroad) and third generation immigrants (i.e. individuals born in the UK, with

    parents born in the UK, but with both grand-parents born abroad). The original study [9] had

    information only on first-generation immigrants, for whom problems of selection and disrup-

    tion due to immigration are a serious concern. While first-generation immigrants in the UK

    could also experience the same issues of selection and disruption due to immigration, for sec-

    ond and third generations these concerns should be more limited. However, there is still a

    potential concern since second and even third-generation immigrants could be discriminated

    against or might feel conflicted between the UK and their parental country of origin.

    Second, the UK is one of the largest immigrant-receiving states with a large variation in the

    country of origin of up to three generations of immigrants.

    Third, the dataset contains detailed information on both actual and self-reported savings

    for a large sample of immigrants, their children and their grandchildren from different coun-

    tries of origin.

    Various contributions to the economics literature have studied the behavior of immigrants

    to show the relevance of cultural values for different economic outcomes, such as living

    arrangements [10], female labor force participation and fertility [11], trust [12] and preferences

    for redistribution [13]. For a review on the relevance of culture on economic outcomes, see

    [14] and [15]. All these contributions study the persistence of cultural traits for first or second-

    generation immigrants. None of the studies mentioned above has been able to go beyond the

    analysis of second-generation immigrants, as the datasets used did not contain any informa-

    tion on the country of origin of one individual’s grandparents. An exception is the study by

    [16] that goes beyond second-generation immigrants and looks at the behavior of first, second

    and ‘higher generation immigrants’ (higher generation in their context are third, fourth or fur-

    ther generation) in the United States using the General Social Survey. Importantly, the authors

    report evidence of persistence and evolution of different types of values and show that some

    cultural traits, such as family and gender values, political views, and deep personal religious

    values, are very persistent. Other traits, instead (such as attitudes towards cooperation, chil-

    dren’s independence, and attitudes towards sexuality) tend to exhibit less persistence. The

    authors do not look at saving behavior in their analysis.

    To study the relevance of cultural norms we link each immigrant to the saving rates from

    their country of origin. We use a measure of savings rate over GDP, calculated from 1990 until

    2010, as a proxy for culture. We attribute the association found in our data between the behav-

    iour of immigrants and the saving rate in the country of origin to differences in cultural beliefs

    across immigrant groups. Looking at various generations of immigrants constitutes a sort of

    “natural experiment”. When migrants move to a new country, they leave behind the economic

    and institutional conditions that determine their saving behavior in the country of origin, they

    however bring with them their cultural beliefs. Savings/GDP at the aggregate level will depend

    on the distribution of beliefs about the importance of savings, and this distribution varies

  • across countries, hence reflecting variation in culture. If this aggregate variable has then

    explanatory power for the variation in immigrants’ saving outcomes, even after controlling for

    their individual economic attributes, only the cultural component of this variable can be

    responsible for this correlation. This is because the economic and institutional environment is

    now the same for immigrants from different countries and it is the one of the United King-

    dom. The mechanisms behind the correlation of saving behavior of different generations and

    saving outcomes in the country of origin can be attributed to intergenerational cultural trans-

    mission, according to which parents tend to transmit their beliefs to their children (see [17]).

    Nonetheless, the measure of savings/GDP from the country of origin proxies an average effect

    of cultural transmission. A substantial heterogeneity can be at play for different immigrant

    groups, for example the frequency of contacts with the country of origin or the size of the com-

    munity of immigrants in the neighbourhood where immigrants live. Unfortunately, the

    Understanding Society Survey does not contain any information on any of these variables, and

    we cannot study in this paper this type of heterogeneity.

    Material and methods

    Variable construction and definition

    Our main sample consists of individuals older than thirteen. We define the first generation as

    immigrants who are not born in the UK; second generation as those who are born in the UK

    but with at least one parent not born in the UK; and third generation, as those who are born in

    the UK to parents both of whom are also born in the UK, but have at least one grandparent,

    who is not born in the UK. This is the formal definition of immigrant generations given in the

    Understanding Society Survey dataset. Natives are those with all grandparents born in the UK.

    The number of observations for each country of origin is provided in the S1 Table of the Sup-

    porting Information.

    Proxy for culture. Our proxy for culture, savings/GDP of the country of origin, is taken

    from the World Bank’sWorld Development Indicators. Gross domestic savings are calculatedas GDP less final consumption expenditures (i.e. total consumption). We pooled data over the

    1990–2010 period to minimize measurement error. The results are however robust to different

    time ranges (for example if we consider the 1990–1999 and 2000–2010 periods separately).

    Saving rates across countries for our sample of interest are also highly correlated in the two

    periods (0.87) and have very similar means (20.3 and 20.7) and standard deviations (7 and

    9.04).

    Outcome variables. We use three measures of saving behavior.

    1. Total amount of saving: This variable is the self-reported “monthly amount of savings”. Thisvariable is available in the Understanding Society Survey dataset for the respondents who

    answers “yes” to the “propensity to save” question reported below. These people were asked

    another follow-up question in wave 2 and wave 4 to collect self-reported data on the

    monthly amount of savings: “About how much on average do you personally manage to

    save a month?”. We take the log of this variable and, in order not to lose observations for

    individuals reporting zero, we added one pound to the total amount reported.

    2. Propensity to save: This is a self reported binary measure of saving behavior, where 1 indi-cates that an individual answers “yes” to the following survey question in wave 2 and wave

    4. “Do you save any amount of your income, for example by putting something away now

    and then in a bank, building society, or Post Office account, other than to meet regular

    bills? Please include share purchase schemes, ISA’s and Tessa accounts.” The person can

    answer either yes or no.

  • 3. Positive Savings: We constructed an objective measure of actual savings by using a large setof wealth variables in the wealth module of the survey in waves 2 and 4. Net worth is defined

    as the sum of housing equity, car equity and liquid financial net worth. We then calculated

    change in “net worth” from wave 2 to wave 4 as [Net worth(w4)−Net worth(w2)]/ 10000.Our variable of interest, “positive savings”, takes the value of the change if the wealth hasincreased between two time periods or zero if wealth has decreased or stayed the same over

    the same period.

    Control variables. Our control variables include age dummies, dummy indicators for

    female and for whether the person is married, number of children, log of monthly total house-

    hold net income, which is a derived variable available in the dataset (This variable can take

    negative values, and it is top-coded +/- £20,000. We added 13771.8 + 1 to all observations

    before taking the log because -13771.8 is the lowest value. This adjustment is done so that we

    do not loose observations when logs are taken). We also control for employment status (we

    include dummies for individuals who are unemployed and out of the labor force, the excluded

    group are the employed), education (we include dummies for secondary education, A-level

    degree, other higher degree, and college and above; the excluded group includes individuals

    with the lowest level of education, “no qualification” or “other qualification”), paternal educa-

    tion (we include dummies for whether the father left school with no qualification, whether the

    father had some qualification, post-school qualification, or college or more; the excluded

    group are fathers who did not go to school) and occupation fixed effects. We also test the

    robustness of our results to the inclusion of a measure of permanent income (S3 Table). This

    measure is calculated using a procedure similar to [18], [19] and, to a certain extent, [20]: we

    regress our measure of log net household income on all individual characteristics, such as flexi-

    ble age dummies, gender, marital status, number of children, education, occupational class,

    region dummies and wave dummies. The predicted income using this regression is used as a

    measure of individual-specific permanent income (i.e. residuals would constitute the transi-

    tory income).

    Descriptive analysis

    Before starting our empirical analysis, we first examine whether there exists a systematic corre-

    lation between saving rates in the country of origin and saving behavior among the three gen-

    erations of immigrants. We report the correlations for the logarithm of the total amount of

    savings among immigrants and saving rates in the countries of origin in Figs 1–3. A number of

    facts are apparent from them. First, saving rates are strongly correlated with savings in the

    country of origin: coming from cultures with high saving rates is reflected in higher saving

    rates among immigrants in the United Kingdom. Second, these correlations are strong, not

    only for immigrants and their children, but also for third-generation immigrants. Finally, Figs

    1–3 also show that the relationship is not driven by a small number of countries.

    Empirical analysis

    The differences in saving rates among immigrants shown in Figs 1–3 could be driven by indi-

    vidual characteristics or family background characteristics or by particular economic condi-

    tions of the place where migrants decide to live. We, therefore, turn to OLS multivariate

    regression estimates of the relationship between saving behavior among immigrants and sav-

    ing in the country of origin. Using a multivariate regression framework allows us to account

    for a host of other factors that may also affect savings. Without appropriate controls, we run

  • the risk of capturing a spurious correlation between the unobserved factors and saving in the

    country of origin.

    Our empirical analysis takes care of these concerns by estimating the following equation:

    Yic ¼ aðSavings=GDPÞc þ bXi þ yXitþdt þ mr þ mr � dt þ εict

    where Yic are our outcomes of interest (the logarithm of the reported amount of savings, adummy indicating whether the individual is saving or not, and savings calculated using differ-

    ences in wealth). Xi and Xit are time invariant and time variant individual controls describedabove. Our specification also includes a full set of wave and regional dummies (δt and μr).These are the baseline controls used in the first three columns of each table. From columns

    4–6 we also add all the non-linear interactions between region and wave fixed effects (μr � δt)to control for regional specific trends that could be driving differences in savings as a result of

    differences in economic conditions. In this specification, we also include a full set of dummies

    for the education of the father, described above. The standard errors are clustered at the coun-

    try of origin level. Descriptive statistics are provided in the S2 Table.

    Results and discussion

    The estimates for saving rates are reported in Table 1. From the regression estimates, we see

    the same pattern emerging as in Figs 1–3. Immigrants coming from countries with high saving

    rates also tend to save more in the United Kingdom. In addition, the importance of culture

    plays a role up until the third generation. The coefficients are not only statistically significant,

  • but they are also meaningful in magnitude. Based upon the estimates from column 1, a one

    standard deviation change in the country of origin savings rate is associated with an increase

    of saving rates of .051 standard deviations in the first generation, .040 standard deviation in

    the second generation and .025 standard deviation in the third. The impact seems to be declin-

    ing across generations. The effect is also meaningful when compared to other economic factors

    such as the level of education: for the first generation, the effect of savings in the country of ori-

    gin is equal to forty-one percent of the effect of having a college degree (for which the beta

    coefficient is equal to 0.104) and fifty-one percent of the effect of income (for which the beta

    coefficient is equal to 0.124). The effect of culture in the regressions with the extended set of

    controls (columns 4–6) shows a similar pattern, but with almost no decline from the first to

    the second generation. The effect on the third generation also loses significance, although the

    size of the coefficient remains of similar magnitude.

    In the Supporting Information, we show that differences in culture are also important to

    explain the propensity to save and we find strong effects, in terms of both magnitude and sig-

    nificance (S4 Table).

    One of the potential concerns with Table 1 is that saving rates might suffer from self-reporting

    bias. To address such a concern, our dataset contains records on individual’s wealth, which allow

    us to calculate individual’s specific savings from wealth differences across time to match the same

    estimates as in Table 1. S5 Table reports the estimates of regressing saving rates based on wealth

    differences from wave 2 to wave 4 on the country of origin savings rates. The right-hand side vari-

    ables are measured in wave 4. The results are consistent with the other two saving measures. The

    effect of culture on the change in wealth has a similar impact across the three generations.

  • Conclusions

    This study examines the effect of culture and its persistence on savings. We show evidence of a

    robust association between immigrant saving behavior and the saving rates in their country of

  • origin that persists up to the third generation. Our results are consistent across different mea-

    sures of savings (two self-reported savings measures and savings calculated as wealth change

    over time). These results go against the prevailing evidence suggesting that culture does not

    play a role in shaping savings behavior, and instead indicate that culture cannot be disregarded

    in the study of saving differences across countries.
